When released to water bodies, for example with chlorinated wastewater, the by-products can have harmful effects on the water body and aquatic organisms. In this Bachelor\u2019s thesis, we examined the toxicity of Scandic Hotel Laajavuori spa\u2019s backwash water. We also explored the possibility of discharging the backwash water to a nearby pond, Vuorilampi. Backwash water is water from the washings of the filters of the pool purification system. Pool water is chlorinated, so the backwash water contains residual chlorine. Toxicity was studied by doing an acute toxicity test and reproduction test using Daphnia magna -water fleas. In the study, the backwash water was found to have harmful effects on the reproduction. The backwash water also affected the immobility and growth of daphnia. Mortality was not affected by the backwash water. The results did not provide an unequivocal answer whether the backwash water could be discharged to Vuorilampi.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2022-03-23T09:59:10Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2022-03-23T09:59:10Z (GMT).
